Colombia Tariffs, Banning Chinese Drones, and Stacie Pettyjohn on Drone Warfare

Emily and Geoff play a quick round of Tariff Tarot to dissect Trump’s tariff threats on Colombia last weekend. Then they dig in to the bipartisan debate over banning various connected products, including drones, from China, and explain why this may be one area of continuity between the Biden and Trump administrations. Finally, Dr. Stacie Pettyjohn, senior fellow and director of the CNAS Defense Program, joins to discuss her research on how drones are changing warfare and why the United States needs to invest in the drone industrial base.
